Enter the volume under pressure and temperature in the reservoir (bbl) and the volume of oil measured under standard conditions (bbl) into the Calculator. The calculator will evaluate the Oil Formation Volume Factor.

## Oil Formation Volume Factor Formula

OFV = Vpt / Vsc

Variables:

• OFV is the Oil Formation Volume Factor ()
• Vpt is the volume under pressure and temperature in the reservoir (bbl)
• Vsc is the volume of oil measured under standard conditions (bbl)

To calculate Oil Formation Volume Factor, divide the volume under pressure and temperature in the reservoir by the volume under standard conditions.

## How to Calculate Oil Formation Volume Factor?

The following steps outline how to calculate the Oil Formation Volume Factor.

1. First, determine the volume under pressure and temperature in the reservoir (bbl).
2. Next, determine the volume of oil measured under standard conditions (bbl).
3. Next, gather the formula from above = OFV = Vpt / Vsc.
4. Finally, calculate the Oil Formation Volume Factor.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

volume under pressure and temperature in reservoir (bbl) = 51

volume of oil measured under standard conditions (bbl) = 40
